Specicaton of Letters Patent. Paftntgd Sept. 26,V l1916 Applicationfiled April 13, 1916. Serial No. 90,906. v.

To all 'wim/m z5 may concern v Be it known that I, JAN Pnirnuszxmwioz, acitizen of the United States, residing at Kulpmont, in the county ofl`lorthumber-` land and State of Pennsylvania, have invented certain newand useful Improvements in Mail-Boxes, of which the following is aspeciication.

rl"his invention relates to certain new and useful improvements in mailboxes. .v

The primary object of the invention is the provision of a depositbox'for mail having the lid thereof automatically locked upon closingthe mail lentrance slot whereby a person unfamiliar Vwith the boX wouldbe unable to gain access thereto.

A further object of the device is to provide a lid lock for a receptacleengageable upon swinging the cover slide of the entrance slot to itsclosing position, Ia spring lock being also arranged for maintaining thelid closed and releasable only by an insei-ted key.

`With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangement of parts hereinafter'more fully described, illustrated in the accompanying drawings, andthen claimed. I

In the drawings forming a part of this application and in which likedesignating characters refer to corresponding parts throughout theseveral views z-Figure 1 is a vertical transverse sectional view throughthe device. in its secured closed position. Fig. 2 is a top plan viewthereofwith the slot plate in its open position partially broken away.Fig. 3 is a sectional view taken upon line III-III of Fig. 1. Fig. 4 isa sectional view taken upon line IV-IV of Fig. 1, and, Fig. 5 is a.detail 'horizontal sectional view taken substantially upon the same lineof section as Fig. 4 and illustrating the key in its released position.

Referring more in detail to the drawings, the mail box broadly consistsin a casing or receptacle 10 rectangular in cross-section having a top11 provided with a 'lid 12 attached thereto by means of hinges 13, thesaid lid being provided with a mail entrance slot 14 positionedlongitudinally there-V through. Laterally projecting ears 15 are carriedby the rear wall 16 of the casing being adapted for rigidly mounting themail box upon any desirable support.

VA U-sliaped keeper 17 is secured interiorly of the casing 10 upon theside wall 18'theie? of being adapted for engagementv by the curved edgeportionk of a diskg19 concentrically secured to a post 20 journaledthrough the lid 12 and having a cover platel 21 for the slot 14 securedto its free end-projectingexteriorly of the said lid.4 A button 22 ispreferably arranged upon the postl 20 between the disk 19 and the lid12, it being thus apparent that the disk19 will be revolved upon(shiftingV the plate 21. Anvinterrupted orflattened side face 23 ,ispro..

videdv for thev disk 19,k the saidV diskbeing in the same plane asthedepression of theY U-shaped'keeper 17 when the lid 12 is closed :wherebythe curved edge of the disk 19will engage within the keeper 17 when theplate 21 is shifted to'covei` the slot 14, as best illustrated in F ig.Y1 ofrthe drawing while the said disk will be released from the keeper 17on account of the interruption in its periphery at the side face 23 whenthe plate is shifted projecting outwardlyV substantially perpendicularto the side edge of the lid 12 as shown in Fig. 2.

It will be thus apparent that when the lid is closed andthe slot 14 isalso closed, the lid will be prevented from being opened by means of theengagement of the disk 19 with the keeper 17 so that a person unfamiliarwith'the mail box willbe ignorant as to the manner-of opening the same.A i

snap lock is also provided for the box which Vis in the form of a springlatch 24 arranged I within the casing 10 and having one end secured asat 25 tothe front side 26 thereof.

The latch 24 is angular in cross-section having a flange 27 adapted toreceive a hook 28 therebeneath, the said hook being carried Vby the lid12 while the latch 24 is connected to the wall 26 by lmeans of a coilspring 29. When the lid 12 is closed, the hook 28is automaticallyengaged by the latch 24. The

casing side 18 is provided with a key-hole 30 in substantial alineinentwithV the latch 24V adapted for the reception of a suitable key 31 whichis adapted to be slidably received 'upon an'angular guide 32 carried bythe contact with the latch 24 for moving theY latch outwardly againstthe tension of the latch and also the spring 29, thus releasing thelatchk flange 27 from the hook 28 and allowing the lid`12't`o be readilyVswung open upon its hinges 13 providing the aforementioned disk 19 isin its released position. A pivoted closure 34 is provided for thekeyhole 30.

While the form of the` invention herein shown and described is What isbelieved to be the preferred embodiment thereof, VVit is nevertheless tobe understood that 'various Yforms, modifications and arrangements of;

' casing having the depression thereof in the Copies of this patent maybe .obtained for five cents each, by addressing the \Commissioner oflPatents,

saine horizontal plane as the said disk `when' the lid is in its closedposition.

2; A inail box provided with a hinged lid hav-ing an entrance slottherein, a pivotedA cover plate for the said slot, a keeper Within thebox, and a locking disk on the innerside of the lid operativelyconnected to tliesaid plate.

3. A mail box comprising a easing having y a hinged lid provided With anentrance slot` therethrough7 a post journaled through'the Vsaid lid, acover'plate for tliesaid slot flatly engaging the outer yface of the lidand hav-L iing one end secured -to the outwardly prow jecting end ofthesaid post, a locking disk having an interrupted side face secured tothe inner end of the said post, a yU-shaped`r ranged uponthe adjacentside of the easing with iespectto the said keeper.

In testimony whereof I affix my signature.-l
